It doesn't install on Windows + MinGW:

> cabal install --global haddock

[ 9 of 33] Compiling Haddock.Utils    ( src\Haddock\Utils.hs,  
dist\build\Haddock\Utils.o )

src\Haddock\Utils.hs:435:8: parse error on input `import'
cabal: Error: some packages failed to install:
haddock-2.8.0 failed during the building phase. The exception was:
ExitFailure 1

This concerns a line with a foreign import:

#ifdef mingw32_HOST_OS
foreign import ccall unsafe "_getpid" getProcessID :: IO Int -- relies on  
Int == Int32 on Windows
#else
getProcessID :: IO Int
getProcessID = fmap fromIntegral System.Posix.Internals.c_getpid
#endif


Adding the line:
   {-# LANGUAGE ForeignFunctionInterface #-}
to the top of file  src\Haddock\Utils.hs helped.
